Dysmyelination of the Cerebral White matter with Microdeletion at 6p25.

ABSTRACT

A 6-year old boy presented with mental retardation, hypotonia, abnormal facies, impaired hearing, protuberant eyes, visual impairment, short stature, Axenfeld- Rieger anomaly, a bicuspid aortic valve, and bilateral sensorineural deafness. CT scan of head suggested dysmyelination of the subcortical and periventricular white matter. FISH revealed a subtelomeric microdeletion encompassing both FOXC1 and FOXF2 loci within 6p25. Dysmyelination of the central nervous system has been infrequently described earlier in patients with 6p25 deletion.
